Abstract

In this work, Na 0.5Bi 0.5TiO 3 (NBT) was used to improve the high temperature dielectric properties of Nb, Co-doped BaTiO 3 (BT). Different x was selected (x = 0, 0.02, 0.04, 0.06, 0.08, 0.1, 0.2, 0.3, 0.4) to optimize the ratio of BT to NBT in (1 - x) BT-xNBT solid solution. The dielectric constant of the original X7R material is about 4900 at room temperature, decreasing to 2500 with NBT addition (x = 0.2). Of important is that the temperature stability was improved with dielectric constant variation being less than ±15% up to 160°C.
